db.collection.getSearchIndexes()

Definition

db.collection.getSearchIndexes()

New in version 7.0: (Also available starting in 6.0.7)

Returns information about existing Atlas Search indexes or Atlas Vector Search indexes on a specified collection.

Important

mongosh Method

This page documents a mongosh method. This is not the documentation for a language-specific driver, such as Node.js.

For MongoDB API drivers, refer to the language-specific MongoDB driver documentation.

Compatibility

This method is available in deployments hosted in the following environments:

MongoDB Atlas: The fully managed service for MongoDB deployments in the cloud

Important

This command is not supported in serverless instances. For more information, see Unsupported Commands.

Syntax

Command syntax:

db.<collection>.getSearchIndexes(<indexName>)

Command Fields

getSearchIndexes() takes this field:

Field	Type	Necessity	Description
`indexName`	string	Optional	Name of the index to return information about. If you omit the `indexName` field, `getSearchIndexes()` returns information about all Atlas Search indexes on the collection.

Access Control

If your deployment enforces access control, the user running getSearchIndexes() must have the listSearchIndexes privilege action on the database or collection:

{
   resource: {
      db : <database>,
      collection: <collection>
   },
   actions: [ "listSearchIndexes" ]
}

The built-in read role provides the the listSearchIndexes privilege. The following example grants the read role on the qa database:

db.grantRolesToUser(
   "<user>",
   [ { role: "read", db: "qa" } ]
)

Output

getSearchIndexes() returns an array of documents. Each document in the array contains the following fields:

Field	Type	Description
`id`	string	Unique identifier for the index.
`name`	string	Name of the index.
`status`	string	Status of the index. For more information, see Atlas Search Index Statuses.
`queryable`	boolean	Indicates whether the index is ready to be queried.
`latestDefinitionVersion`	document	Describes the version of the index.
`latestDefinitionVersion.version`	integer	Version number associated with the index definition. When you update an index definition, the version number increments automatically.
`latestDefinitionVersion.createdAt`	date	Time when the current index definition was created.
`latestDefinition`	document	The most recent definition for the index. For more information, see Search Index Definition Syntax.
`statusDetail`	array of documents	Contains the status of the index on each search host (`mongot`).
`statusDetail.[n].hostname`	string	Hostname of the corresponding `mongot`.
`statusDetail.[n].status`	string	Status of the index on the corresponding `mongot`.
`statusDetail.[n].queryable`	boolean	Indicates whether the index is ready to be queried on the corresponding `mongot`.
`statusDetail.[n].mainIndex`	document	Contains status information about the active index on the corresponding `mongot`. For details, see Index Status Details.
`statusDetail.[n].stagedIndex`	document	Contains status information about an index being built in the background on the corresponding `mongot`. This field only appears if you are building a new index to update an existing active index. For details, see Index Status Details.
`synonymMappingStatus`	string	Status of the index's synonym mappings. This field only appears if the index has synonyms defined. Can be one of the following values: `BUILDING` `FAILED` `READY` The returned status is a summary of the synonym mappings on each individual `mongot`.
`synonymMappingStatusDetail`	array of documents	Contains the status of the index's synonym mappings on each search host (`mongot`). This field (and its subfields) only appear if the index has synonyms defined.
`synonymMappingStatusDetail.[n].status`	string	Status for the corresponding synonym mapping across all `mongot` processes.
`synonymMappingStatusDetail.[n].queryable`	boolean	Indicates whether the corresponding synonym mapping can support queries across all `mongot` processes.
`message`	string	Describes an error for the synonym mapping, if applicable. Only appears if the `status` for this synonym mapping is `FAILED`.

Index Status Details

The following table describes the embedded fields of the following documents: - statusDetail.[mongot].mainIndex - statusDetail.[mongot].stagedIndex

The fields describe the index status on a specific mongot.

Field	Type	Description
`status`	string	The state of the index generation on the corresponding `mongot`.
`queryable`	boolean	Indicates whether the index generation is ready to be queried on the corresponding `mongot`.
`synonymMappingStatus`	string	The state of the index generation's synonym mappings on the corresponding `mongot`. Only present if the index has synonyms defined.
`synonymMappingStatusDetails`	document	Contains the status of the index's synonym mappings on the corresponding `mongot`. This field (and its subfields) only appear if the index has synonyms defined. For more information, see Synonym Mapping Details.
`definitionVersion`	document	Describes the index definition version that this index generation is being built with.
`definitionVersion.version`	integer	Version number that the index generation is using on the corresponding `mongot`. When you update an index definition, the updated index builds with an incremented version number.
`definitionVersion.createdAt`	date	Time when the index definition was created.
`definition`	document	The definition that this index is being built with.

Synonym Mapping Details

The following table describes the embedded fields of the following objects:

statusDetail.mainIndex.synonymMappingStatusDetails.<synonymMapping>
statusDetail.stagedIndex.synonymMappingStatusDetails<synonymMapping>

Field	Type	Description
`status`	string	Status for the synonym mapping across on the corresponding `mongot` process.
`queryable`	boolean	Indicates whether the synonym mapping can support queries on the corresponding `mongot` process.
`message`	string	Describes an error for the synonym mapping, if applicable. Only appears if the `status` for this synonym mapping is `FAILED`.

Atlas Search Index Statuses

The status field in the getSearchIndexes() output can be one of the following:

Status	Description
`BUILDING`	The following scenarios can cause an index to be in the `BUILDING` state: Atlas is building the index or re-building the index after an edit. Atlas Search cannot keep up with indexing changes to the collection. In this case, Atlas rebuilds the index in the background. When the index is in the `BUILDING` state: For a new index, Atlas Search cannot use the index for queries until the index build is complete. For an existing index, Atlas Search uses the old index definition for queries until the index rebuild is complete. An index in the `BUILDING` state may be queryable or non-queryable.
`DOES_NOT_EXIST`	The index does not exist. An index in the `DOES_NOT_EXIST` state is always non-queryable.
`DELETING`	Atlas is deleting the index. An index in the `DELETING` state is always non-queryable.
`FAILED`	The index build failed. Indexes can enter the `FAILED` state due to an invalid index definition. An index in the `FAILED` state may be queryable or non-queryable.
`PENDING`	Atlas has not yet started building the index. An index in the `PENDING` state is always non-queryable.
`READY`	The index is ready and can support queries. An index in the `READY` state is always queryable.
`STALE`	The index is queryable but has stopped replicating data from the indexed collection. Searches on the index may return out-of-date data. Indexes can enter the `STALE` state due to replication errors. An index in the `STALE` state is always queryable.

Examples

These examples demonstrate how to:

Return All Search Indexes
Return a Single Search Index

Return All Search Indexes

The following example returns all Atlas Search indexes on the movies collection. The movies collection contains two search indexes: default and synonym_mappings.
